...my son had the same dilemma with a training offer from FTE but he elected the SS route instead saving himself in excess of £40,000. He reduced his training time by almost 5 months too. The FTE course takes about 14 months however he completed the entire syllabus in just over 9months - granted he had a PPL already.
Is SS an acronym for self sponsored? If so, I don't understand your post, and think you might be confusing "self sponsored" with "modular"? There are lots of self sponsored guys training at FTE. It's my understanding that the terminology means the guys find the (not insignificant) funds themselves and aren't tagged to any particular airline.
Or have I got the wrong end of the stick?
